BOB-SLED.

SPECIFICATION forming part of Letters Patent No. 628,949, dated 31115 18, 1899- Application filed December 19, 1898. Serial No. 699,705. (No modeh) Be it known that I, HARRY MACCLOUD, a subject of the Queen of Great Britain, residing at Groton, in the county of Tompkins and State of' New York, have invented a new and useful Bob-Sled, of which the following Ais a specification.

The invention relates to bob-sleds.

The object of the present invention is to improve the construction of bob-sleds and to provide a simple, inexpensive and efficient one which will possess great strength and durability and be adapted to have either a rack, box, or reach mounted upon it.

A further object of the invention is to improve the construction for connecting the draft mechanism with a bob-sled and to enimprovements in able a pole or a pair of thills to be readily coupled to and uncoupled from the upper structure or framework of the sled.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective view of a bob-sled constructed in accordance with this invention. Fig. 2 is a longitudinal sectional View of the same. Fig. 3 is a transverse sectional view. Fig. 4 is a detailperspective view of one of the inner side plates.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 1 designate a pair of runners pivotally mounted by transverse bolts 2 or other suitable fastening devices between inner and outer side plates 3 and 4, arranged in pairs and located at opposite sides of the sled, as clearly illustrated in Fig. 3 of the accompanying drawings. The runners, which may be constructed of either wood or metal or a combination of such material, are provided between their ends with upwardly-extending segmental enlargements 5, which are arranged between the inner and outer side plates, and when the runners are constructed of wood they are preferably provided with suitable wearplates or similar devices to prevent them from becoming worn by rubbing against the side plates.

The outer side plates, which may be made solid, as shown, or of' open-work, are provided at their upper edges with outwardly-extending flanges 6, which are bolted or otherwise secured to the lower faces of longitudinal bars 7, and the inner plates, which have-similar longitudinal flanges 8 at their central portions, are split at opposite sides thereof and bent awayfrom the runners to provide inner inclined braces 9. The inclined braces 9 are provided at their upper ends with horizontal flanges 10, secured to the lower faces of the longitudinal bars 7 adjacent to the inner edges thereof, and by this construction the runners are firmly supported against lateral movement and are held in true parallelism.

The front portions 11 of the longitudinal bars 7 are tapered or reduced, as shown, and the rear portions are connected by transverse beams 12, which support acentrally-arranged fifth-wheel 13, designed to be constructed in any suitable manner, according to the character of work for which the bob-sled is designed, and adapted to permit the front bob to be coupled to a rack, a box, or a reach.

The tapered or reduced portions 11 of the longitudinal bars 7 are located in advance of the transverse beams, and they are supported by draft-bars 14 and 15, arranged in pairs at The inner draft-bar 14, which is secured to the inner edge or face of the longitudinal bar 7 and to thefront edge or face of the front transverse beam, is arranged at an angle to the longitudinal bar and is angularly bent, as shown. The front portion 16 of the inner draft-bar is curved upward and terminates at a point opposite the front end of the outer draft-bar 15, and the front terminalsof these draft-bars are perforated to form eyes 17 and 18 for the reception of a coupling-bolt for connecting a tongue or a pair of thills to the bob. The rear portions of the inner draftbars firmly brace the bob, and by arranging the draft at the point shown the pole or thills are arranged clear of the body or upper portion of the bob-sled and greater' space or freedom for the attachment of a boX, rack, or reach is secured.

The bolts 19 and 20, which connect the front and rear portions of the inner and outer plates, are provided with spacing-sleeves 21, which prevent the plates from binding against the runner and at the same time enable the bolts to hold the plates firmly the desired distance apart. The front bolts also serve as a means for securing the lower ends ot' the outer draft-rods to the inner plates.

Theinvention has the following advantages The sled-bob herein shown and described is simple and comparatively inexpensive in construction, and it possesses great strength and durability. The coupling devices are located at a point where they will not interfere with the rack, box, or reach that may be coupled to the bob, and by coupling the pole or thill to the longitudinal bars of the frame which connects the plates the runners are permitted to have afree pivotal movement to conform to the configuration of the surface of the ground Without affecting the horizontal alinement of the thill-couplings. The front portions ot the longitudinal bars are Yfirmly braced and supported by the draft-bars and the inner draft-bars are arranged to brace the front of the bob securely.

Changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

What is claimed is- 1. A device of the class described comprising the inner and the outer plates arranged in pairs, the inner plates being provided at opposite sides of their centers with inclined braces, a frame connected with the tops of the plates, and runners pivoted between the plates, substantially as described.

2. A device of the class described comprising a pair of longitudinal bars, inner and outer plates arranged in pairs and secured to and depending from the said bars, the inner plates being provided with inclined braces, runners pivoted between the plates, and means for coupling the longitudinal bars with a pole or a pair of thills, substantially as described.

3. A device of the class described comprising inner and outer plates arranged in pairs, a frame secured to the plates and provided with forwardly-extending longitudinal bars,A runners pivoted between the plates, and the draft-bars arranged in pairs, secured to the inner and outer faces of the longitudinal bars and to the frame and the inner plates, said draft-bars being extended beyond the longitudinal bars and l provided with eyes and adapted to have a pole or a pair of thills coupled to them, substantially as described.

4. A device of the class described comprising inner and outer plates arranged in pairs, longitudinal bars having the plates secured to them, transverse beams connecting the longitudinal bars and adapted to support a fifthwheel, runners pivoted between the plates, the outer draft-bars secured to the outer faces of the longitudinal bars and to the inner plates, the inner draft-bars secured to the inner faces of the longitudinal bars, arranged at an angle thereto and secured to the adjacent transverse beam, said draft-bars being extended beyond the longitudinal bars and provided with eyes for the reception of coupling-bolts, substantially as described.

5.v A device of the class described comprising a pair of longitudinal bars, means for connecting the same, inner and outer plates secured to the longitudinal bars and provided at their upper edges with horizontal flanges, the inner plates being split at opposite sides of the center and bent outward to form inclined braces, runners pivoted between theinner and ou ter plates, and the combined draftbars and braces arranged in pairs and extending from the longitudinal bars, substantially as described.

In testimony that I claim the foregoing as my own I have hereto afxed my signature in the presence of two witnesses.
